FreeBSD ‘No Space Left on Device’ Error – Troubleshooting Guide

freebsdshellunix

When I login with root, and run "mkdir test", the system says "No space left on device". But if I login with other user, it goes well. 

[/root]df -h

[/root]mkdir test

/: create/symlink failed, no inodes free
mkdir: .ssh: No space left on device

Your root user's home is on the root filesystem (/). That filesystem is not full, so I have to assume you are out of inodes. Check the output of df -i. Here's a reference about how to diagnose this and what you can do to fix it. Hint: you need to move files to another filesystem or create a new filesystem to use.
